The invention belongs to the technical field of ship equipment, and discloses a cargo oil pump sweeping system and a ship, the cargo oil pump sweeping system comprises a cargo oil header pipe, a cargo oil branch pipe and a sweeping suction port, a cargo oil pump is installed on the cargo oil header pipe, and the cargo oil pump sweeping system further comprises a sweeping branch pipe, a sweeping line header pipe, a first sweeping line branch pipe, a negative pressure system and a purging pipeline. One end of the sweeping branch pipe extends into the suction well, the other end of the sweeping branch pipe is connected with the cargo oil branch pipe, and a sweeping valve is arranged on the sweeping branch pipe; one end of the first line sweeping branch pipe is connected with the cargo oil branch pipe, the other end of the first line sweeping branch pipe is connected with the line sweeping header pipe, and a first line sweeping valve is arranged on the first line sweeping branch pipe; the negative pressure system is connected with the cargo oil header pipe and can provide negative pressure for the cargo oil header pipe; the purging pipeline is connected with the cargo oil header pipe and can provide compressed gas for the cargo oil header pipe, and a purging valve is arranged on the purging pipeline. The cargo oil pump sweeping system can deeply purge raffinate of a suction well in a cargo oil tank and pipeline raffinate in a cargo oil header pipe and a cargo oil branch pipe, and minimization of sweeping residual volume is achieved.
